To all to/1011i it may 00720671.

Be it known that I, lViLLiAM Sonnonnnn, a citizen of the United States,residing at Dewey, in the county of Washington and State of Oklahoma,have invented certain new and useful Improvements in Clamps, of whichthe following is a specification.

This invention relates to coupling connections employed in pumps such asare used on the end of pull rods for pumping oil wells and for othersimilar uses.

The invention has for its object to provide a simple, strong and durablecombination clamp to be used with pump rods in which one bolt may beemployed instead of four.

lVith the above and other objects in view, this invention consists .inthe construction, arrangement and combination of parts, all ashereinafter more fully described,claimed and illustrated in theaccompanying drawings, in which z- Figure 1 is a view of the combinationclamp constructed in accordance with this invention. Fig. 2 is a view ofthe clamp with one of the clamping plates removed. l ig. 3 is a detailview of one of the clamping plates. Fig. f is an end view of the clampwith the link and bolt removed. Fig. an end view of the device shown inFig. 1.

In carrying out the invention. a pair of metallic clamping plates 1,shown as rectangular, are employed. Each of the plates 1 is formed atone end with a pair of semicircular passageways 2 terminating in atransverse recess 3, said passageways and recesses being locatedadjacent to each end of the plate 1. The plate 1 is further provided inits opposite end with a semi-circular passageway l extending into theplate about half way therein, and with a trans verse recess 5 extendingacross said passageway t, the latter being located upon one side of thecenter of the plate. When the two plates so constructed are placedtogether as shown in Figs. 1 and 41-, the passageways and the recessesin each plate will coincide, and together form holes with the transversesockets across each hole. The plates are clamped together by means of abolt hole 6 centrally located in each plate and a headed bolt 7 passingthrough said hole and pro- Specification of Letters Patent.

vided with clamping nut 8. Secured between said plates and one endthereof is a metallic loop or link 9 provided at its ends with circularheads or lugs 10 which are seated in the sockets formed by the aliningrecesses 3, the arms of the link 9 extending through the holes formed bythe {dining pas sageways 2. Secured to the opposite end of the clampingplates between the same is one end of a rod 11 which projects into thehole formed by the semi-circular passageways at in said plates and hasformed upon the inner end thereof a head 13 located in the socket formedby the aliniug recesses 5 in the plates 1.

The ends of the link 9 and the end of the rod 11, with its head 13 beinglocated between the plates 1 and clamped thereby are held securely inplace by means of the bolt 7 and nut 8.

It will be seen by the foregoing construction that a strong; andeffective clamp is provided for clamping together a link and a bolt andthat a simple construction is afforded wherein only a single bolt isemployed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

A clamp consisting of a pair of metallic plates each provided with abolt hole in the center thereof, and at one end a pair of semicircularpassageways with a transverse recess therein, a U-shaped link providedwith a head on each end thereof and adapted to seat in said passageways,the other end of said plates being provided with a passageway and havinga transverse recess formed in. the end thereof, and a rod seated in saidpassageway provided with a head on the end thereof and said head being;of smaller length than the transverse recess, allowing; for lost motionof said rod, and a bolt passing through the hole in said plates adaptedto secure the plates in registration with each other.

In testimony whereof I affix my signature in presence of two witnesses.
